Pelargonium plant named ‘Duegbofbbl’

ABSTRACT

A new and distinct cultivar of Ivy Geranium plant named ‘Duegbofbbl’, characterized by its upright to outwardly spreading and rounded plant habit; vigorous growth habit; freely basal branching habit; freely flowering habit; large dark and light red purple bi-colored double flowers; and good garden performance.

Botanical designation: Pelargonium peltatum.

Cultivar denomination: ‘DUEGBOFBBL’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ivy Geranium plant, botanically known as Pelargonium peltatum, and hereinafter referred to by the name ‘Duegbofbbl’.

The new Ivy Geranium plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new vigorous Ivy Geranium plants with numerous attractive double-type flowers.

The new Ivy Geranium plant is a naturally-occurring whole plant mutation of a proprietary selection of Pelargonium peltatum identified as code number P08-2853-006, not patented. The new Ivy Geranium plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of the parent selection in a controlled greenhouse environment in Rheinberg, Germany in May, 2013.

Asexual reproduction of the new Ivy Geranium plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2013 has shown that the unique features of this new Ivy Geranium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Ivy Geranium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duegbofbbl’. These characteristics in combination distinguish ‘Duegbofbbl’ as a new and distinct Ivy Geranium plant:

-   -   1. Upright to outwardly spreading and rounded plant habit.     -   2. Vigorous growth habit.     -   3. Freely basal branching habit.     -   4. Freely flowering habit.     -   5. Large dark and light red purple bi-colored double flowers.     -   6. Good garden performance.

Plants of the new Ivy Geranium differ primarily from plants of the parent selection in flower color as plants of the parent selection have solid red purple-colored flowers.

Plants of the new Ivy Geranium can be compared to plants of Pelargonium peltatum ‘Duegbofmer’, disclosed in U.S. Plant Pat. No. 26,103. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Ivy Geranium differed primarily from plants in the following characteristics:

-   -   1. Plants of the new Ivy Geranium were slightly smaller than         plants of ‘Duegbofmer’.     -   2. Plants of the new Ivy Geranium had smaller leaves than plants         of ‘Duegbofmer’.     -   3. Plants of the new Ivy Geranium had larger flowers than plants         of ‘Duegbofmer’.     -   4. Plants of the new Ivy Geranium and ‘Duegbofmer’ differed in         flower color as plants of ‘Duegbofmer’ had solid dark red         purple-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Ivy Geranium plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Ivy Geranium plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Duegbofbbl’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Pelargonium production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time three weeks after planting and were 13 weeks old when the photograph and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
